# RTC_SetDate

## C Specification

  `#include <nitro/rtc.h>`

      RTCResult RTC_SetDate( const RTCDate*  date );

## Description

This function writes date data to the real time clock. It sends date data to ARM7 and returns the process result once it is received. This is a synchronous version of `RTC_SetDateAsync`.

## Cautions

Do not define define parameter values of nonexistent years, months, or days. However, you may specify a day of the week that does not match the actual calendar. This function requires a PXI interrupt for synchronization. It cannot be used in situations where PXI interrupts are prohibited. Because applications cannot change the date, use this API only for debugging during development.

## Arguments

`date` | Pointer to `RTCDate` containing date information to be set.

## Return Values

If the request succeeds, it returns 0.
If the request fails, it returns some numeric value other than 0.
